Detecting Traffic Speeds With Sign Alert

April 13, 2020

Reflectivity enhances sign visibility, but a TraffiCalm’s Sign Alert system goes an extra step to raise driver awareness of speed. Here’s a deeper look at what this affordable system can do and why it’s a significant upgrade from traditional traffic control solutions.

Purpose of Sign Alert

Sign Alert is a traffic control enhancement system designed to make roads safer by increasing sign visibility and alerting drivers about their behavior. The package comes with a WiFi connection known as TC Connect, which allows you to detect driving speeds through modern specialized Internet of Things (IoT) technology.

Key Advantages

  • Retrofits any existing traffic sign
  • MUTCD compliant
  • Solar or AC powered with replaceable batteries
  • Easy installation
  • 24/7 flashing LEDs
  • Connectivity allows for gathering traffic data for analysis
  • Useful for speed detection

Basic Model

TraffiCalm, an Idaho based electronic traffic control device manufacturer, offers a basic and advanced version of Sign Alert, which gives you the flexible option to meet your budget and needs. The basic system consists of 24/7 LED lights, which can be programmed to flash in a single, alternating, or unison mode. You can also set flashing patterns for standard, rapid, bright, pulse, or emergency operation.

Advanced Model

Both the basic and advanced models are radar compatible and can be powered with solar or standard alternating current. The advanced version has all of the features of the basic model with the added advantage of network compatibility with TC Connect.

TC Connect does not require software or an app and operates on any platform or mobile device. It does not require extra costs to operate and does not need to be connected with a WiFi hotspot, since it provides its own self-sustaining internet connection within a short range. Furthermore, it’s a secure system using an assigned network security key.

As soon as you power up the Sign Alert system, it can be seen through any browser enabled device and works with Windows or Mac operating systems. After two hours, the WiFi connectivity expires, but can be reactivated by initiating another power cycle. Although it cannot be controlled from any remote location, TC Connect can be controlled from anywhere within 100 feet of the Sign Alert device.

Setup is simple, as it only requires entering the security key then opening the TC Connect web page. You will then be prompted by a SetUp Wizard, which will walk you through the Sign Alert settings process.

TC Connect Details

You have the option of five different operating modes once TC Connect is ready to use:

  1. 24/7 Flashing
  2. Day Only
  3. Night Only
  4. Button Operated
  5. Radar Activated

Another option is to set the Flasher Rate of LEDs from 60 to 180 flashes per minute. You can customize the flashing pattern for Standard, Bright-pop, Pulse, Emergency or Push 2 Cross Flash settings. If radar is enabled, you can set LED flashing to minimum or maximum speed detection thresholds that shut off flashing.

The radar is able to detect vehicle speeds from a distance up to 450 feet. This range gives the driver a chance to see the approaching sign and adjust speed if necessary. Sign Alert components including the battery, controller or collaborator, are designed to last up to five years with a warranty, along with the LED Flasher Rings. Meanwhile, the LEDs have a guaranteed lifespan of 100,000 hours.
